IMPROVEMENT IN HANDLE ATTACHMENTS TO SCRUBBING-BRUSHES.

Specification forming part of Letters Patent No. l 56,158, dated October20, 1874; application filed August 1, 1874.

To all whom it may concern:

Be it known that I, HARRISON P. Hoon, of the city of Indianapolis, Stateof Indiana, have invented an Improvement in Attaching Handles toScrubbing-Brushes, of which the following is a specification:

My invention relates to an improved device for attaching handles toscrubbing-brushes, or other scrubbing devices, whereby the handle may bereadily attached to or detached from the scrubber, and the position ofthe handle in relation to the scrubber be altered at will, ashereinafter set forth.

The accompanying drawings illustrate my invention.

Figure l is a vertical section. plan.

In Fig. 1, a is a plate, which is in form the frustum of a cone, the topsurface of which is at right angles with a line passing centrally fromapex to base of the cone, and the base of which is at an acute anglethereto, making the plate higher at one side than the other, as shown. 0is a conical socket, the inside of which fits the conical sides of theplate a, and on one side of which, at a suitable angle, is formed asocket, b,-for the reception of a handle. s is athumb-screw, which,passing through the center of the conical socket 0, is there secured insuch manner that it is free to turn, but will not fall out, which resultis accomplished either by means of a pin passed through the screw,inside the socket, or by riveting, as shown. It screws into the plate a,and has a shoulder, a, which bears on the socket, and serves to fastenthe two together, as shown.

The operation of my device is as follows: The plate a is first screwedor otherwise fastened to the back of an ordinary scrubbingbrush; Thesocket I), having inserted therein a handle of suitable length, is nowplaced with its conical socket a over the plate a, and the screw 8screwed into the plate, when the two are firmly fastened together by theconical sur- Fig. 2 is a faces of the plate and socket being forcedtogether. By slightly loosening the thumbscrew the handle may now beplaced so as to stand at right angles with the length of the brush, orparallel therewith, or. at any intermediate angle, as desired, and therefastened by a slight turn of the screw, thus adapting it to use moreconveniently along the sides of a room.

It will be observed that, on account of the base of the plate a notbeing at right angles with the cone of which it is a frustum, the planeof revolution of the socket containing the handle is not parallel withthe surface of the brush, but at an acute angle thereto. This is for thepurpose of adjusting the angle which the handle forms with the surfaceof the brush, the handle when standing over the higher side of the platea forming an obtuse angle with the surface of the brush, and being thenin a suitable position for use upon the floor, and, when standing overthe lower or thin side of the plate, forming a more acute angle, andbeing in a suitable position for use upon the baseboards, or the upperparts of door or window casings.

When it is desirable to use the brush without any handle, the handle maybe removed by turning the screw out of the plate. It will then remainfastened in the socket c. The plate, having no rough projections, is notin the way, and will not hurt the hand in using the brush.

I claim as my invention The combination and arrangement of the conicalplate a, socket c, and thumb-screw s, for the purpose of attaching ahandle to a scrubbingbrush, substantially in the manner and for thepurpose above set forth.

HARRISON P. HOOD.
